(b) Calculate the charge that flows through the battery.
#87: The flash unit in a camera uses a special circuit to “step up” the 3.0 V from the batteries to 300 V, which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes 10 ms, and the average power dissipated in the flashlamp is 105 W. What is the capacitance of the capacitor?
